Abstract
The purpose of this utility model is that disclosing a kind of power transformer folding core structure, it includes core body, and the core body is four frame pentastyle structures being made of iron core column, upper yoke and lower yoke；Compared with prior art, four frame pentastyle structures being made up of iron core column, upper yoke and lower yoke, effectively reduce the length of magnetic path of iron core, the window height for reducing iron core, reduces the weight of iron core, reduces the body height of iron core, it is simple in structure, it extremely uses, realizes the purpose of this utility model, realize the purpose of this utility model.
Description
Technical field
The utility model is related to a kind of folding core structure, more particularly to a kind of power transformer folds core structure.
Background technology
Power transformer is a kind of static electrical equipment, is for by the alternating voltage of a certain numerical value（Electric current）Become frequency
The different voltage of the identical another or several numerical value of rate（Electric current）Equipment.When first winding passes to alternating current, just generate
The magnetic flux of the magnetic flux of alternation, alternation is acted on by iron core magnetic conduction, and AC electromotive force is just induced in secondary winding.Secondary induction
The height of electromotive force is related with the number of a secondary winding the number of turns, i.e., voltage swing is directly proportional to the number of turns.
The iron core of power transformer is stacked made of pressing by multi-disc silicon steel sheet.But existing this structure, iron
Core seam quantity is 6, and iron core seam crossing air gap is larger, and iron core no-load current is larger.
It is accordingly required in particular to a kind of power transformer folds core structure, it is above-mentioned existing to solve the problems, such as.
Utility model content
The purpose of this utility model is to provide a kind of power transformers to fold core structure, not for the prior art
Foot, iron core seam quantity are reduced to 3, effectively reduce iron core seam crossing air gap, reduce the no-load current of iron core.
Following technical scheme may be used to realize in the technical issues of the utility model is solved：
A kind of power transformer folding core structure, which is characterized in that it includes core body, and the core body is served as reasons
The four frame pentastyle structures that iron core column, upper yoke and lower yoke are constituted.
In one embodiment of the utility model, coil windings are provided in the iron core column.
In one embodiment of the utility model, the end set of the iron core column has side yoke.
In one embodiment of the utility model, the core body is stacked pressing by multi-disc silicon steel sheet and forms.
The power transformer of the utility model folds core structure, compared with prior art, by iron core column, upper yoke and
The four frame pentastyle structures that lower yoke is constituted effectively reduce the length of magnetic path of iron core, reduce the window height of iron core, reduce
The weight of iron core reduces the body height of iron core, simple in structure, extremely uses, and realizes the purpose of this utility model.
The characteristics of the utility model, sees the detailed description of the drawings of the present case and following preferable embodiment and obtains clear
Ground understands.
Description of the drawings
Fig. 1 is that the power transformer of the utility model folds the structural schematic diagram of core structure；
Fig. 2 is that the power transformer of the utility model folds the side schematic view of core structure.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment
As depicted in figs. 1 and 2, the power transformer of the utility model folds core structure, core body, the iron core sheet
Body is four frame pentastyle structures being made of each iron core column 10, upper yoke 20 and lower yoke 30.
In the present embodiment, coil windings are provided in the iron core column 10（Do not show in figure）.
In the present embodiment, the end set of the iron core column 10 has side yoke 40.
In the present embodiment, the core body is by multi-disc silicon steel sheet（Do not show in figure）Stacked pressing forms.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention, the utility model
Claimed range is defined by the appending claims and its equivalent thereof.
